The radiographic anatomy of the IMAs is described based on bilateral selective arteriography in 100 patients with coronary artery disease. The right and left IMAs were identical in caliber in their mid portions in 94% of cases. Fifteen percent of the IMAs measured less than 2 mm in luminal diameter at the level of the fourth costal cartilage. The side branches showed a great deal of variability and asymmetry in their origin and distribution. The understanding of the radiographic anatomy of the IMA and its branches is helpful in preoperative appraisal and is crucial for postoperative evaluation of the IMA grafts.
基于对100例冠心病患者进行的双侧选择性动脉造影，描述了胸廓内动脉（IMA）的放射学解剖结构。在94%的病例中，左右IMA的中段管径相同。15%的IMA在第四肋软骨水平处管腔直径小于2mm。侧支在起源和分布上表现出很大的变异性和不对称性。了解IMA及其分支的放射学解剖结构有助于术前评估，对于IMA移植物的术后评估至关重要。
